{"abstract":"The FAA is superseding Airworthiness Directive (AD) 2023-11- 08, which applied to all Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 required maintenance actions, including a high-pressure valve (HPV) seal integrity test, repetitive replacement of the HPV clips, revision of the existing airplane flight manual (AFM), and implementation of updates to the FAA-approved operator's minimum equipment list (MEL). This AD was prompted by the determination that the replacement intervals required by AD 2023-11-08 must be reduced to address the unsafe condition. This AD continues to require the actions in AD 2023-11-08. This AD also reduces the HPV clip replacement intervals, requires an additional revision of the existing AFM for certain airplanes, and limits the installation of HPV clips, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2025/02/28/2025-03293.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"90 FR 10853","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective April 4, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-0766","Project Identifier MCAI-2023-00711-T","Amendment 39-22963","AD 2025-04-05"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-0766-0006"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-0766-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2025-02-28","updated_at":"2025-02-28T08:57:03.140-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-0766-0005","allow_late_comments":false,"id":"FAA-2024-0766-0005","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2024-0766","title":"MCAI-2023-00711-T; Airbus SAS Model A330-841 and -941 airplanes; high pressure valve clip"}],"document_number":"2025-03293","effective_on":"2025-04-04","end_page":10856,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/02/28/2025-03293.xml","html_url":"https://www.federalregister.gov/documents/2025/02/28/2025-03293/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-03293?publication_date=2025-02-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-02-28/2025-03293/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":175,"last_updated":"2026-10-24 22:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-02-28/pdf/2025-03293.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-03293.pdf?1740663921","publication_date":"2025-02-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/02/28/2025-03293.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-0766-0006"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-0766-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2024-0766","supporting_documents_count":2,"docket_id":"FAA-2024-0766","document_id":"FAA-2024-0766-0005","regulation_id_number":"2120-AA64","title":"MCAI-2023-00711-T; Airbus SAS Model A330-841 and -941 airplanes; high pressure valve clip","checked_regulationsdotgov_at":"2025-03-01T12:55:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":10853,"subtype":null,"title":"Airworthiness Directives; Airbus SAS Airplanes","toc_doc":"Airbus SAS Airplanes","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":90}
